PRINTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 758,210, dated Apri. 26, 1904:.

Application filed June 24, 1903. serial No. 162.868. (No model.) i

To all whom, it incty concern:

Be it known that I, JOHN JQA. JONES,H. citizen of the United States, residing at Green Island, county of Albany, and State of New drawings, and the reference characters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figures.

Figure 1 of the drawings is a plan view of the face of my improved printing apparatus, one end'of the type-holdingbars being shown in horizontal section upon the broken line 1 1 in Fig. 2. Fig. 2 is an end view of the same. Fig. 3 is a vertical section of the same, taken on the brokenline 3 3 in Fig. 1. Fig. 4 is a view, on an enlarged scale, of a preferred form of set-screw and washer-plate for locking the type-holding bars in position upon the bedplate. Fig. 5 is a face View, partly broken away, of a modified form of apparatus. Fig.

6 is aview in perspective of one of the grooved printing-blocks. Fig. 7 is a view in perspective of a portion of one of the key-plates.

The object of my invention is to provide a simple and convenient form of printing apparatus adapted for use by hand permitting the use of changeable types. 7

My apparatus in its preferred form permits .the use of types of different sizes, styles, or.

fonts in the same form and also permits the arrangement of the types in lines at any desired distance apart.

My invention is shown in its preferred form in Figs. 1, 2, 3, and 4, referring to which 1 is a base-plate provided with a handle 2, whereby the plate can be manipulated in making impressions from the types mounted thereon; The changeable types 3 are supported upon the base-plate between the bars 4 and 5, the opposite ends of each of which are adapted to receive the .opposite edges of the base-plate, upon which the bars are adjustably secured vparted thereto.

the bar by amovement of separation.

each by a set-screw 6. The set-screw 6 is inserted through the end of the bar into engagement with the edge of the base plate or an interposed washer-plate 7, as shown in Fig. 3.

A preferred form of set-screw and washerplate is shown in Fig. 4, the parts being connected togetheriby a ballz'and-so'cket joint at 8.

By loosening the'set-screws 6 the bars can be moved to any desiredposition. upon the with grooves 10, adapted to receive lockingkeys mounted on certain of the bars, as the bars 5, whereby the types are secured against displacement in use. I

The base of the rubber type is preferably made of sponge-rubber and provided with ribs or tongues 25, which are secured by cement incorresponding grooves in the end of the wooden block 9, as illustrated in Fig. 6.

The bars 5 are cut away to receive the keyplates 12, each provided with a plurality of diagonal slots 13, adapted to receive the respective guide-pins 14, upon which the slotted plates are adapted to play and whereby two of said plates arranged along the opposite sides ofa bar 5 can be moved toward or from each other by longitudinal movements im- The plates are thus adapted to be withdrawn within the bar by a movement of approach and to be projected beyond When the key-plates are thus projected beyond the bar, they are adapted to enterthe grooves 10 in the types arranged adjacent thereto and serve to hold such types securely in position by engagement therewith of the milled or roughened edge 24 of the plate. In Fig. 1 types are thus shown held by the key-plates on opposite sides of the bar 5 shown in section, said types being held between said bar 5 and the bars 4 on opposite sides of the same,

and in the same figure the key-plates are represented as withdrawn within the bar 5 shown in plan.

The key-plates are preferably made a little longer than the bars 5, so that longitudinal reciprocating movements can be imparted to the plates by merely pressing upon the ends thereof,which project at one end or the other of the bar.

The key-plates may be held in locking position in any known manner, as by means of a button 19 pivoted upon the end of the bar at 15 and adapted to be swung into engagement with the ends of the key-plates after the same have been forced inwardly into line with the end of the bar.

It is only necessary to provide the alternate bars 5 with key-plates, the types being provided with grooves in their opposite sides, and when desired a single key-plate may be employed.

In Fig. 5' I have shown the invention adapted for printing curved lines of characters.

In this construction the bars 16 and 17 are concentrically curved, the grooved types being located therebetween and locked in position by means of a flexible key 18, which is forced when under tension into the grooves in the side of the types. One end of the flexible key is fixed at 20 upon the bar 16, and the other end is connected with a nut 21 upon a screw 22, mounted in the other end of the bar,

whereby the slack in the flexible key can be taken up. When released, the flexible key becomes slack and occupies the space 23 within the bar 16.

My improved construction permits of the rapid changing of the types, as well as variation in the distance apart of the type-supall the types in two lines are thus simultaneously locked or simultaneously unlocked.

What I claim as new, and desire to secure by Letters Patent, ,is V

1. In a printing apparatus, the combination with a base-plate; and type-supporting bars thereon; of types provided with side grooves arranged between said bars; and a key movably mounted upon one of said bars adapted to be projected from the bar to enter the side grooves in said types to lock the same in position.

2. In a printing apparatus, the combination with a base-plate; and type-supporting bars thereon, one adjustable toward another; of types provided with side grooves arranged between said bars; and a key movably mounted upon one of said bars adapted to be projected from the bar to enter the side grooves in said types to lock the same in position.

3. In a printing apparatus, the combination with a base-plate; and type-supporting bars thereon, of types provided with oppositelylocated side grooves arranged between an intermediate bar and bars on opposite sides of the same; and a pair of keys each movably mounted on said intermediate bar adapted to be projected from opposite sides of the same into the side grooves in said types respectively to lock the same in position.

4. In a printing apparatus, the combination with a base-plate; and type-supporting bars thereon; of types provided with side grooves arranged between said bars; a keyplate mounted on one of said bars by means of pins inserted through diagonal slots in the keyplate, and adapted when projected beyond the side of the bar to enter the side grooves in the type to lock the same in position; means for imparting longitudinal movements to said key-plate whereby the same is projected laterally beyond the bar; and means for locking the key-plate against longitudinal movement.

In testimony whereof I have hereunto set my hand this 5th day of June, 1903.

I J. J. A. JONES.
